Defines 2 functions


Interface: part_of_admin_tree  - X-Ref

Interface for anything appearing in the admin tree

The interface that is implemented by anything that appears in the admin tree
block. It forces inheriting classes to define a method for checking user permissions
and methods for finding something in the admin tree.

locate($name)   X-Ref
Finds a named part_of_admin_tree.

Used to find a part_of_admin_tree. If a class only inherits part_of_admin_tree
and not parentable_part_of_admin_tree, then this function should only check if
$this->name matches $name. If it does, it should return a reference to $this,
otherwise, it should return a reference to NULL.

If a class inherits parentable_part_of_admin_tree, this method should be called
recursively on all child objects (assuming, of course, the parent object's name
doesn't match the search criterion).

param: string $name The internal name of the part_of_admin_tree we're searching for.
return: mixed An object reference or a NULL reference.

prune($name)   X-Ref
Removes named part_of_admin_tree.

param: string $name The internal name of the part_of_admin_tree we want to remove.
return: bool success.

search($query)   X-Ref
Search using query

param: string $query
return: mixed array-object structure of found settings and pages

check_access()   X-Ref
Verifies current user's access to this part_of_admin_tree.

Used to check if the current user has access to this part of the admin tree or
not. If a class only inherits part_of_admin_tree and not parentable_part_of_admin_tree,
then this method is usually just a call to has_capability() in the site context.

If a class inherits parentable_part_of_admin_tree, this method should return the
logical OR of the return of check_access() on all child objects.

return: bool True if the user has access, false if she doesn't.

is_hidden()   X-Ref
Mostly useful for removing of some parts of the tree in admin tree block.

return: True is hidden from normal list view

show_save()   X-Ref
Show we display Save button at the page bottom?

return: bool

Interface: parentable_part_of_admin_tree  - X-Ref

Interface implemented by any part_of_admin_tree that has children.

The interface implemented by any part_of_admin_tree that can be a parent
to other part_of_admin_tree's. (For now, this only includes admin_category.) Apart
from ensuring part_of_admin_tree compliancy, it also ensures inheriting methods
include an add method for adding other part_of_admin_tree objects as children.

add($destinationname, $something, $beforesibling = null)   X-Ref
Adds a part_of_admin_tree object to the admin tree.

Used to add a part_of_admin_tree object to this object or a child of this
object. $something should only be added if $destinationname matches
$this->name. If it doesn't, add should be called on child objects that are
also parentable_part_of_admin_tree's.

$something should be appended as the last child in the $destinationname. If the
$beforesibling is specified, $something should be prepended to it. If the given
sibling is not found, $something should be appended to the end of $destinationname
and a developer debugging message should be displayed.

param: string $destinationname The internal name of the new parent for $something.
param: part_of_admin_tree $something The object to be added.
return: bool True on success, false on failure.

Class: admin_category  - X-Ref

The object used to represent folders (a.k.a. categories) in the admin tree block.

Each admin_category object contains a number of part_of_admin_tree objects.

__construct($name, $visiblename, $hidden=false)   X-Ref
Constructor for an empty admin category

param: string $name The internal name for this category. Must be unique amongst ALL part_of_admin_tree objects
param: string $visiblename The displayed named for this category. Usually obtained through get_string()
param: bool $hidden hide category in admin tree block, defaults to false

locate($name, $findpath=false)   X-Ref
Returns a reference to the part_of_admin_tree object with internal name $name.

param: string $name The internal name of the object we want.
param: bool $findpath initialize path and visiblepath arrays
return: mixed A reference to the object with internal name $name if found, otherwise a reference to NULL.

search($query)   X-Ref
Search using query

param: string query
return: mixed array-object structure of found settings and pages

prune($name)   X-Ref
Removes part_of_admin_tree object with internal name $name.

param: string $name The internal name of the object we want to remove.
return: bool success

add($parentname, $something, $beforesibling = null)   X-Ref
Adds a part_of_admin_tree to a child or grandchild (or great-grandchild, and so forth) of this object.

By default the new part of the tree is appended as the last child of the parent. You
can specify a sibling node that the new part should be prepended to. If the given
sibling is not found, the part is appended to the end (as it would be by default) and
a developer debugging message is displayed.

param: string $destinationame The internal name of the immediate parent that we want for $something.
param: mixed $something A part_of_admin_tree or setting instance to be added.
param: string $beforesibling The name of the parent's child the $something should be prepended to.
return: bool True if successfully added, false if $something can not be added.

check_access()   X-Ref
Checks if the user has access to anything in this category.

return: bool True if the user has access to at least one child in this category, false otherwise.

is_hidden()   X-Ref
Is this category hidden in admin tree block?

return: bool True if hidden

show_save()   X-Ref
Show we display Save button at the page bottom?

return: bool

set_sorting($sort, $asc = true, $split = true)   X-Ref
Sets sorting on this category.

Please note this function doesn't actually do the sorting.
It can be called anytime.
Sorting occurs when the user calls get_children.
Code using the children array directly won't see the sorted results.

param: bool $sort If set to true children will be sorted, if false they won't be.
param: bool $asc If true sorting will be ascending, otherwise descending.
param: bool $split If true we sort pages and sub categories separately.

get_children()   X-Ref
Returns the children associated with this category.

return: part_of_admin_tree[]

__get($property)   X-Ref
Magically gets a property from this object.

param: $property
return: part_of_admin_tree[]

__set($property, $value)   X-Ref
Magically sets a property against this object.

param: string $property
param: mixed $value

__isset($property)   X-Ref
Checks if an inaccessible property is set.

param: string $property
return: bool

Class: admin_root  - X-Ref

Root of admin settings tree, does not have any parent.

__construct($fulltree)   X-Ref

param: bool $fulltree true means all settings required,

purge_children($requirefulltree)   X-Ref
Empties children array, and sets loaded to false

param: bool $requirefulltree

Class: admin_externalpage  - X-Ref

Links external PHP pages into the admin tree.

See detailed usage example at the top of this document (adminlib.php)

__construct($name, $visiblename, $url, $req_capability='moodle/site:config', $hidden=false, $context=NULL)   X-Ref
Constructor for adding an external page into the admin tree.

param: string $name The internal name for this external page. Must be unique amongst ALL part_of_admin_tree objects.
param: string $visiblename The displayed name for this external page. Usually obtained through get_string().
param: string $url The external URL that we should link to when someone requests this external page.
param: mixed $req_capability The role capability/permission a user must have to access this external page. Defaults to 'moodle/site:config'.
param: boolean $hidden Is this external page hidden in admin tree block? Default false.
param: stdClass $context The context the page relates to. Not sure what happens

locate($name, $findpath=false)   X-Ref
Returns a reference to the part_of_admin_tree object with internal name $name.

param: string $name The internal name of the object we want.
param: bool $findpath defaults to false
return: mixed A reference to the object with internal name $name if found, otherwise a reference to NULL.

prune($name)   X-Ref
This function always returns false, required function by interface

param: string $name
return: false

search($query)   X-Ref
Search using query

param: string $query
return: mixed array-object structure of found settings and pages

check_access()   X-Ref
Determines if the current user has access to this external page based on $this->req_capability.

return: bool True if user has access, false otherwise.

is_hidden()   X-Ref
Is this external page hidden in admin tree block?

return: bool True if hidden

show_save()   X-Ref
Show we display Save button at the page bottom?

return: bool
